Hello guiles. Nice build. Just curious though, how did you measure/scribe/build an angle within .2 degrees? Especially a soffit face with compound angles in 3 planes at the edges.(you haven't shown how the soffit face interfaces with the adjacent planes yet) And what parameters gave you this angle and the height of the monitor in the first place? The reason I ask, is I've been told by one Studio designer, in his opinion, monitors should never be more than 5 degrees in vertical alignment because of thie Pinna effect.... http://www.sweetwater.com/expert-center ... innaEffect Although, as usual, another designer disagreed with the afore mentioned designer, and remarked 8 degrees was his limit. :mrgreen: When I asked him what told him the angle of the monitors in the first place, he said "the height" which confused me, so I asked him what told him the height? He replied.."the distance"...hmmmm, shades of beating around the bush eh? :mrgreen: I tried to pin him down even more but he chastised me for asking "proprietary" questions. :roll: That tells me something. :mrgreen:Wound up being a 13.8º angle.. for the upper speakers.
I rounded up to 14 degrees for the angle. Perhaps there is some hard fast issue restricting angles. Perhaps when I fire them up I will find it to be true and adjust. My choice of angle is based on the restrictions of distance and height. If there turns out to be some undesirable effect, I can adjust them accordingly. My Mackies will be my main monitors nonetheless. The Angled monitors will be for client appeasement and getting the bottom right... Who knows, if I find the sound desirable they may become my mains.... My decision was further mitigated by the height of my head in relation to the drivers of the monitor being used. I hope that helps, if not I will put up my over simplified diagram.Hello guiles. Nice build. Just curious though, how did you measure/scribe/build an angle within .2 degrees?

Excuse my ignorance. I don't understand your question. Could you rephrase... If you saw the photo I posted.. Use that as a basis for your question. All measurements were based on average head/ear height with relation to a seated mix position.But I'm just curious. Without a vertical section through the monitors its difficult to see how this angle establishes your equalateral triangle apex HEIGHT, without knowing the centerline of the monitor height and horizontal distance to it. Like this.
I noticed you never did complete your vapor barrier. As a rule, an unbroken barrier is >required< in order for it to display the attributes of a barrier. Not only is yours "broken" it is missing entirely in some of the areas. This is only mentioned in that when you have moisture issues somewhere down the short road, you may have an avenue to trace the path to what is or is not creating this problem. A solid unbroken moisture barrier is a requirement, anything less is unacceptable. Vapor will creep around the broken areas much in the same way anything else water related will take the path of least resistance. It should be noted that this product is closed cell, more a thermal break than specifically used for a barrier. Unless in the case of SIP(Structurally Insulated Panel) or ICF to be more exact, of which this application does not meet that definition. I appreciate having lowered costs, we all benefit from this. But follow through and strict adherence to contemporary building technique is as important as anything in a basement application.FInally starting to raise the 1st layer of drywall in the Control room. Dont fear, the Rockwool is going in later this week. I needed to place the lower 1st layer for resizing my plans.External image, not preserved — original: http://www.simplykristal.org/studiobuild/IMG_0452External image, not preserved — original: http://www.simplykristal.org/studiobuild/IMG_0453External image, not preserved — original: http://www.simplykristal.org/studiobuild/IMG_0454External image, not preserved — original: http://www.simplykristal.org/studiobuild/IMG_0455
